Abstract
NEW MATERIAL:A compound expressed by formula I (either of R1 and R2 is H and the other is -CH2COCH3). USE:An intermediate for antibiotic substances. PREPARATION:A compound expressed by formula II (either of R1 and R2 is H and the other is OH) is reacted with a compound expressed by formula III (Y is Cl, Br or I) or formula IV and the resultant compound is then subjected to ring opening using a ring opening reaction reagent, such as a compound expressed by formula V. The obtained compound is subsequently reacted with triphenylphosphine and diethyl carbonate in THF to afford the aimed compound expressed by formula I.
